*new* 9. Six of us stay in our house and we use to manage the home expenditures in the following way - We have an expenditure sheet where there is one column per person. whenever someone spends something that is common for all, he needs to enter the amount under his name in the expenditure sheet. At the end of the month, sum of amount spent by all the people added together would be the total expenditure. This total amount divided by six should be each person's contribution. Now whoever did not completely contribute his part would give money to person who has spent more. Last week four of us went to a movie and one person spent rs600 that day. This 600 needs to be shared only by four people who went for the movie. The question is how much amount should be written under each person's column, so that the month end calculation remains the same.
